Not into stuff like that myself but I would have thought the purpose of nipple rings was to show that you have nipple rings. Put on a tight shirt and walk proudly through the library with your chest out like a proud pigeon kind of thing.
But I guess one solution is to get extra piercings on your chest and stomach so people won't be able to tell which piercing is the actual nipple piercing.
